Question

1. refer to the fungus and algae relationship in model 2. a. is there a benefit for one of the organisms or for both? b. is either the fungus or the algae harmed by this relationship? c. which other relationship in model 2 is similar to that between the fungus and the algae? 11. refer to the shark and remora relationship in model 2. a. in the shark and remora relationship, is there a benefit for one of the organisms or for both? b. is either the shark or the remora harmed by this relationship? c. which other relationship in model 2 is similar to that between the shark and the remora? read this! symbiotic relationships are identified by how they affect the organisms involved. the three types of sym - biotic relationships are listed below. • mutualism: both organisms benefit from the relationship. • parasitism: one organism benefits and the other is harmed. • commensalism: one organism benefits and there is no effect on the other. 12. using the information from the read this! box, label each of the relationships in model 2 as mutualism, parasitism or commensalism. 13. with your group, choose one of the organism pairs from model 2 and justify why you categorized the relationship as you did.

Explanation:

10a. In the fungus - algae relationship, it is mutualism as both benefit.
10b. No organism is harmed in a mutualistic relationship.
10c. Need to refer to Model 2 for a similar relationship.
11a. In the shark - remora relationship, the remora benefits (gets food scraps and transportation) while the shark is generally unaffected, which is commensalism.
11b. The shark is not harmed and the remora benefits without harming the shark.
11c. Need to refer to Model 2 for a similar relationship.

1. Identify each relationship in Model 2 based on the definitions of mutualism (both benefit), parasitism (one benefits, one is harmed), and commensalism (one benefits, no effect on the other).
2. For example, if choosing the shark - remora pair, it is commensalism because the remora benefits by getting food and transportation while the shark is neither helped nor harmed.

Answer:

10a. Both organisms benefit.
10b. No.
10c. Refer to Model 2.
11a. The remora benefits, the shark is unaffected.
11b. No.
11c. Refer to Model 2.

1. Identify relationships according to definitions.
2. Justify based on organism - pair's interaction.
